Tiic Active Principles of the Seeds of Rivea corymbosa and Ipomoea violacea. Harvard Botanical Museum Leaflets 20, 194 (1963). 

So far cyclotides have been discovered in plants from the Violaceae (violet), Rubiaceae (coffee), and Cucurbitaceae (cucumber) families " and have been divided mainly into two structural subfamilies called the Mobius and bracelet cyclotides. These two cyclotide subfamilies are distinguished by the presence of a ar-proline residue in loop 5 for the Mobius subfamily. ° ° On the basis of their trypsin inhibitory activity, the two cyclotides MCoTi-I and MCoTi-II from the seeds of the tropical vine Momordica cochmchinensu form a third subfamily, referred to as the trypsin inhibitor subfamily of cyclotides. No other cyclotides have this activity.

Viola spp. (Violaceae), and Iris spp. (Iridaceae). The identification by Terahara et al. of / -coumaryl linked to galactose in delphinidin 3-[6-(ii-p-coumaryl)galactoside] isolated from leaves of red flower tea, Camellia sinensis, is really outstanding. 

Violet leaf absolute is obtained by solvent extraction, via the concrete, from the leaves of Viola odorata L. (Violaceae), which is grown predominantly in southern France. 

Ergine, molecular formula C16H17N3O, is the amide of D-lysergic acid, and commonly known as LSA or LA-111. It is an ergoline alkaloid that occurs in various species of the Convolvulaceae, and in some species of fungus. Rivea corymbosa (ololiuqui), Argyreia nervosa (Hawaiian baby woodrose) and Ipomoea violacea (tlitliltzin) are three major sources of this alkaloid. 

Taxonomically, the genus Ipomoea is extremely difficult. The binomial Ipomoea tricolor has already crept into the limited literature that has groyrn up in connection with this second kind, of ololiuqui. Inasmuch as some confusion may result in the use of two names— ipomoea tricolor and I. violacea- we should point out that, after a study ofplant material and the taxonomic history of these binomials, I am in agreement with the American specialist in the Convolvulaceae, H. D. House (House, H. D. The North American species of the genus Ipomoea in Ann. N.Y. Acad. Sci. 18 C19083 259), that both names actually refer to one polymorphic species. In this case, then, the older name is Ipomoea Violacea L. Sp. Pl. (1753) 161, which should be used in preference to its synonym I. tricolor Cav. Ic. Pl. Par. 3 (1794) 5, t. 208.
